Why don't back-up lights work? - Camry Toyota Cars & Trucks

check the main earth wire near the battery. and one near the rear of the lights. unbolt them and clean the connectors up put some grease on them after. then check again. remember that when the earth wires come off the radio code will be needed to reset the the radio. be safe and take the battery off.

do they work if you put on the head lights. ? do they work when you step on the brake pedal?

I have a 2003 Buick lesabre limited my inside lights don't work

There is a shorted wire somewhere in that circuit. Check to see if any wires are pinched under a bracket or brace where he was working. I have seen it where it was a light bulb the was bad. Need someone familiar with a volt/ohm meter to help trace problem. Good Luck. You did not state where he had been working.

Left hand side of the transmission is the back up light switch on the top jump the 2 wire if the back then works replace the switch

dash light fuse and back feed through a bulb

Open the boot, then remove the cover of the back light then replace the bulb.

Hi, there is no relay, and the plate light run off the same fuse as the tail lights. The problem must be in the wiring or sockets in the back of the truck.

Replace tail light fuse first. I think you have multiple problems.

you will need to check the wiring under the bumper where the trailer wiring is with a test light and with the different lights working.you will probably have to move back in the wiring by 6" and retest until you find were the loss of power is.you don`t say if all the lights don`t work or just certain ones.the brown wire is the tail light,green is the right signal light,yellow is the left signal light and white is the ground wire.you could have broken wires at the trailer hook up itself.
